Dr Jeremy London, a board-certified heart surgeon specializing in general, vascular, and thoracic surgery, has directly addressed the long-standing question: does drinking in moderation add years to your life? His answer challenges popular belief and highlights evolving scientific evidence.
The Myth of Moderate Drinking Benefits
"That used to be the story: a glass of wine a day and you would live longer," said Dr London on his TikTok account. "And I'm not here to tell you that a single drink is going to hurt you. I'm going to tell you that the story is incomplete." He explained that earlier studies compared drinkers to non-drinkers, but many non-drinkers had quit due to illness, creating a flaw that made moderate drinkers appear healthier. "If you remove this flaw then the benefit shrinks dramatically," he added.
However, Eric Rimm, professor of epidemiology and nutrition at the Harvard TH Chan School of Public Health, offered a contrasting view: "There's good evidence that, in general, moderate drinkers who average one to two drinks a day tend to live longer. Whether that is directly linked with alcohol, other lifestyle factors, or some combination is still being explored."
Alcohol's DNA-Damaging Effects
Dr London emphasized the biological impact: "When you drink alcohol you convert it to acetaldehyde, a compound that directly damages DNA. Now, agencies that place tobacco as a carcinogen also put acetaldehyde in this same category." He noted that no health agency has found a benefit to drinking alcohol. "What they have identified is that a little is better than a lot and none is better than a little." He urged informed decisions: "If you're going to drink, don't drink because you think it's going to add years to your life."
In a previous video, Dr London described alcohol as "toxic to every cell in your body" and called removing it from his life "one of the most transformative decisions I've made as an adult." He reserved his harshest criticism for another beverage, which he termed "liquid death," advising: "Just don't drink them. Period. Done."
Alcohol and Cancer Risk
Alcohol is one of only two foods believed to directly cause cancer, alongside processed meats. Cancer Research UK states: "We know for definite that processed meat is a cause of cancer. We are as sure of this link as we are for other proven causes of cancer, like tobacco and alcohol." The organization adds that all types of alcohol increase cancer risk because the alcohol itself causes damage, even in small amounts.
A recent report by the then-surgeon general of the US Public Health Service linked alcohol use to at least seven types of cancer: mouth, throat, larynx, esophagus, breast, liver, and colon and rectum. The report warned that even light or moderate consumption can raise cancer risk. Dr Ernest Hawk, vice president and head of the division of Cancer Prevention and Population Sciences at the University of Texas MD Anderson Cancer Center, told the New York Times: "There is no safe level of alcohol when it comes to cancer risk."
Is Red Wine Beneficial?
Red wine is often highlighted for potential health benefits due to its association with the Mediterranean diet and its content of polyphenols and antioxidants. However, the British Heart Foundation (BHF) notes that other foods like grapes, blueberries, and strawberries provide antioxidants without alcohol's negative effects. BHF-funded research from 2018 concluded that the risks of alcohol consumption on heart and circulatory diseases outweigh the benefits, and drinking above recommended limits harms health. The BHF states: "It's therefore not a good idea to drink wine to protect your heart."
